The five stages of sex organ growth and penis development are described below:

Stage 1: Childhood

Stage 1 is childhood, before puberty begins. Your sex organs do not change very much during this stage. As the rest of your body grows, the penis, scrotum, and testicles grow a little bit larger, too, but not by very much. What growth there is takes place very slowly. The testicles are usually less than 3 ml in size. You won’t have any pubic hair yet. Boys usually don’t grow pubic hair until Stage 2 or later.

Stage 2: Testicles and Scrotum Enlarge

Stage 2 is the beginning of puberty. A boy reaches Stage 2 when his testicles and scrotum begin to enlarge. During childhood, these sex organs grow very slowly. When puberty hits, they start growing at a much faster rate. If your testicles are 4 ml or larger in size you have probably reached Stage 2 and started puberty.

The penis itself doesn’t get much larger in this stage. The biggest change is in the size of the testicles and scrotum. As the testicles grow larger, the scrotum gets longer. The testicles and scrotum hang lower. The skin of the scrotum gets thinner and looser. The scrotum is more baggy and wrinkled. The testicles no longer fill the scrotal sac. The skin of the scrotum has a new “feel” to it. The color changes too. The skin of the scrotum reddens or gets darker in color.

Most boys develop their first pubic hairs during this stage. But many boys don’t develop their first pubic hairs until Stage 3 or

Boys typically reach Stage 2 when they’re ten to twelve years old, but there are many boys who start this stage when they are only nine. There are also many who don’t start until they’re thirteen or nearly fourteen. There are also some perfectly normal and healthy boys who get to Stage 2 even earlier than the age of eight or later than age fourteen.

This stage may last anywhere from just a few months to more than two years. On the average, it lasts about a year.

Stage 3: The Penis Grows Longer

Stage 3 begins when the penis starts to grow longer. It doesn’t get much wider during this stage. The biggest change is in the length of the penis.

The skin of the penis and scrotum continues to deepen in color in this stage. The scrotum and testicles also continue to grow during this stage.

If your pubic hair didn’t start growing during Stage 2, you may notice your first pubic hairs during this stage. If you already have pubic hair, it may get darker and curlier during this stage.

Most boys reach this cage between the ages often and fourteen. The average age for starting Stage 4 is twelve or thirteen. This stage usually lasts anywhere from a couple of months to a year and a half.

Stage 4: The Penis Grows Wider

In Stage 4, the penis grows wider and the glans becomes more developed. The penis also continues to grow longer but the major changes are in its width and in the glans. The skin of the scrotum and penis continues to darken in color. The testicles continue to grow and the scrotum hangs lower. Most boys have pubic hair when they start Stage 4. But there arc some who don’t develop pubic hair until they reach this stage.

Boys typically start Stage 4 when they are thirteen or fourteen years old. But many boys are only eleven or twelve when they start this stage. There are also many boys who arc fifteen, sixteen, or seventeen before they reach this stage. Here again, there are a few perfectly healthy normal boys who fall outside these age ranges. This stage usually lasts anywhere from six months to two years.

Stage 5: Adult Stage

This is the final, mature stage. The testicles are fully grown. They are usually about 1¾ inches long and between 14 and 27 ml n size. The scrotum is also fully developed. The skin of the scrotum and penis has gotten even deeper in color.

The penis is now fully developed. As with other parts of the body, the size of the penis varies from one person to the next. Boys typically reach Stage 5 when they are fourteen to sixteen years old. But some boys reach this stage when they’re only twelve or thirteen and others not until they’re older than sixteen. As with the other stages some normal boys will fall outside the age ranges I mentioned here.

im thirteen and my penis is quite smaller compared to other people my age . in this day and age it can be really humiliating, you tend to get your trousers pulled down by other people and its not very funny. The fact that people can find it as a joke even though they should know it could happen at any age between 12 and 16. Im just really embarrased

Well, I'm 15.. In April ill be 16, just now noticing a slight change in length, testicles seem normal but,, the whole 'length and width' thing? That's reaally what I'm hopping for.. :| for those who get made fun of? I know your feel. 10th grade in rural community is heartless.

My name is zane and im only 14 bout to be 15 my penis when not hard is only 7 inches when it is hard its around 9 inches. But the point is is when u give it to ya girl is all that matters is that u plzz her.... give it to her the best u can go balls deep if u have to...but penis size does not matter just as long as ur proud of him for doing the hard work... if u know what i mean.. haha

idk if this happends to alot of people but somtimes you reach a point in your life when most of your friends start to lose there virginity and your still a virgin because of your penis growth and that really sucks !

Im 14 years old and my dick is 5 inches when resting and 8.5 inches when erected my testicles are preety big i play soccer and my girlfreind loves the sizes and gets the job done down there if you know what.i mean well im glad that my penis is king of the thrown and i think it will keep growing :)

I love my penis! I am only 12 and it's 9 inches long. I love it cause when it gets hard it is 12 inches long. My testicals are hanging and i got hair all over. Guess im lucky cause my girlfriend has already seen down there. If you know what i mean.She loves it! And i love it too.A bit more thickness would be awesome!

I am 11, I am pretty sure I've hit puberty, i am growing hair down in the cave and my dick is growing a little bit. Soft it is only two inches, hard it is around three. sad right. Hey, at least i am having erections! Wait is anyone else 11 and has a fucking dick that that small, if your older than me and have a dick as big as me, to bad for you. see you puberty hiters

Has anyone else seen Jonah Falcon's "It's Too Damn Big"( Jonah Falcon has the largest dick ever) song. I wish I had on as big as his. HOLY SHIT. I just read its over 13 inches when hard, that's fucking huge, how does his dick fit any where! That guy must be proud.

Firstly, I do not think that this guide is that representative or informative for a lot of boys as it doesn't mention the foreskin at all. All the pictures are of circumcised boys and a foreskin plays a massive role during puberty and sex! It fails to mention the fact that the foreskin may not be retractable until they hit puberty or maybe even later as it is fused to the head of the penis. This article would be much more informative if they at least acknowledged the foreskin and how it changes.

Secondly, Hahaha oh my word, so many boys are lying here about their penis size. Come on guys, the average penis size is between 5 and 6 inches. I highly doubt you're 10 or 11 inches long. 10 or 11 inches isn't even the best size as a woman's vagina is only 5 inches long - so anymore than that and you could hurt her.

Take it seriously or not, this is very informative and as a curious woman, all shapes and sizes are good. Those bullshit stories shouldn't get anyone down. This isnt porn, it's reality and an average penis is more welcomed than a giant, scary, possibly painful (and possibly a lie). Learn about the female anatomy and sex and when its your time, remember to be gentle and always wear a condom! Real women dont worry about penis size, they hope for technique and good communication in bed.

I'M 15 GOING ON 16 (JANUARY) AND I'M AROUND 8 INCHES. I'M REALLY WIDE TOO. AND I SATISFY MY GIRL REAL GOOD. :D SOOOO GOOD SHES CRIES,BITES&WHIMPERS. SHE CAN'T HANDLE IT. BUT SHE BE ASKING FOR IT. SO I GIVE IT TO HER. I DON'T LIKE THAT IT HURTS HER THO. MY POOR BABE. :(( :((

Me and my roommates are currently 21 and 22 and we are just wondering when we will get our dad dicks, anyone that can tell us please do, we are worried that we'll be stuck with stage 3-4 goobs for the rest of our lives.

I kind of randomly stumbled onto this site and am a bit older, but I thought I would weigh in anyway. First, I call BS as some have on a lot of the aspiring Dirk Digglers posting on here. What I want to say though is that I developed late (like 15 or 16 before I really started to grow [height wise], voice changing, etc..), and I don't remember when and how my genital development occurred, but I was always concerned about my "size" at the time, and I still am in a weird way. Flaccid, I'm probably 2.5" or 3" tops. Erect though, I'm about 7.5". Naturally, there's a lot of skin folds and room for expansion, but from what I've seen and how other guys talk, I kind of feel this is unusual. I've been with about a half a dozen women in my life, and I don't think there's been one that hasn't commented on how "big" I was, and it's mostly been in reference to my girth which is a good thing, I guess. Still, I avoid changing/showering around other guys because it doesn't seem that way, and I really don't think saying, "You should see it hard," will have the desired effect. Just thought I would give my experience/perspective.

As a side note, this always makes me think of the shower scene in Lucas (80s Corey Haim movie — not some porno) for those who know what I'm talking about.

It's perfectly normal, both size and the fact that you like to wank.You may even have orgasms before reaching puberty. They will be dry, but still feel really good. When reaching puberty, you will begin to have spontanious erections all the time, and your urge to wank will grow more and more.... But enjoy it and have fun :)

I'm 14, 15 in January and my testicular sack is hanging lower and my testicles are starting to get bigger. My penis hasn't grown very much, it's around 1.5 to 2 inches is this normal also it had a little extra skin is that normal

OK guys, 3 things. First, nobody here should be ashamed of their penis size. A true woman doesn't care how big the penis of the man they love is. Second, I think quite a few people here are exaggerating about the size of their penis. It's impossible for anyone's penis to be 12, 13, 14 or 15 inches long. Maybe you measured in centimeters by accident... :^) And third, there were at least three people who insisted they were 3, 4, and 5 years old and their penises were 14, 10 and 12 inches long. Seriously guys, that is impossible. Did you mean to say that you were 13, 14 and 15 years old, or were you only joking?

I'm 13 and hard im about between 3 1/2 and 4 inches and my balls are like to hairy ping pong balls. But when flacid sometimes it varies between 3 inches and 1. Is that normal. Some guys in my hockey team are around 5-6 inches Flacid!!!!!Someone, Please seriously respond.

Remember that a woman has to pass a 7 or 8 pound baby thru her vigina. So this should put your mind at eas about size of your penis. Instead of worrying about your size (which i kno is smaller then even a 5 pound baby) start learning about a womans anatomy down there and find out where her pleasure center is. I.e. clitoris

I was just born the othr night and i feel so good with my penis. its about 15 inches rest and when erect it passes my fucking heead! my chick is also quite happy with it, how ever, we tried anal and i felt high pain at the tip of my penis when going balls to the walls sorta speak. when i took it out it was red and bleeding. do you think she might have digested any of my penis? thanks
